Enum StringMatcher 

pub enum StringMatcher {
    All,
    Exact(String),
    Fn(Box<dyn Fn(&[u8]) -> bool>),
}

Matcher for strings and bytes.

Variants

All

Matches any strings.

Exact(String)

Matches strings exactly.

Fn(Box<dyn Fn(&[u8]) -> bool>)

Tests matches by arbitrary function.

Implementations

impl StringMatcher

pub const fn all() -> Self

Matcher that matches any strings.

pub fn exact(src: impl Into<String>) -> Self

Matcher that matches src exactly.

pub fn is_match(&self, haystack: &str) -> bool

Returns true if this matches the haystack string.

pub fn is_match_bytes(&self, haystack: &[u8]) -> bool

Returns true if this matches the haystack bytes.

pub fn filter_btree_map<'a, K: Borrow<str> + Ord, V>( &self, map: &'a BTreeMap<K, V>, ) -> impl Iterator<Item = (&'a K, &'a V)>

Iterates entries of the given map whose string keys match this.

pub fn filter_btree_map_as_deref<'a, K, V>( &self, map: &'a BTreeMap<K, V>, ) -> impl Iterator<Item = (&'a K, &'a V)>

where K: Borrow<K::Target> + Deref + Ord, K::Target: AsRef<str> + Ord, str: AsRef<K::Target>,

Iterates entries of the given map whose string-like keys match this.

The borrowed key type is constrained by the Deref::Target. It must be convertible to/from str.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
